The historiography of international law, as most of us have learnt it, has been presented as a narrative that progressively found its consecration in the State, as developed through the experiences and practices of Western actors during a succession of mostly European events. The result is necessarily a eurocentric corpus of knowledge. However, one can only wonder how and why such a system was globalized: what was the place of non-European actors and events in the formation and production of international law? Was it simply one of a “periphery’s” replication of the discourses of an imperial, civilizing “core”? It is precisely in opposition to this outlook that Arnulf Becker Lorca, fellow at Harvard University’s Institute for Global Law and Policy, seeks to refocus the discipline to effect cognitive justice in his monograph, Mestizo International Law. The proposition is to acknowledge the central role played by non-Western actors in the formation of the doctrines and principles of International Law. The conclusions of the author point to a need for a correction of the eurocentric distortions propagated in the discipline to recognize the discipline’s hybrid origins. The author’s goal, in his own words, is to provide “a global and intellectual history of a mestizo international law”, an argument with postcolonial/decolonial overtones, that definitely fits into the Third World Approaches to International Law (TWAIL) movement.
